Acoustical Design and Analysis of Rooms

Acoustical Design and Analysis of Rooms for Speech Reinforcement
Large and small room acoustical considerations for speech intelligibility, signal-to-noise problems, and application specific requirements. Designs for room size, shape, finish materials selection and electro-acoustic systems. Applications include voice amplification, speech privacy (noise masking), industrial communications, and high noise level environments. Predictions and on-site measurements of the percentage of loss in articulation of consonants (%ALCons) and Speech Transmission Index (STI), two common figures of merit.

Acoustical Design and Analysis of Rooms for Music Quality
Large and small room acoustical considerations for reverberation characteristics, early-to-late energy ratio, Initial-Time-Delay Gap (ITDG), sound reflections, room modes, and noise levels. Evaluation of relationships between sound energy levels, arrival times, and direction of arrival. Comparison of musical acoustical relationships such as warmth, texture, intimacy, etc. Applications include, among others, rehearsal band rooms, recording studios, concert halls, and worship spaces.

Acoustical Design and Analysis of Rooms for Noise Control
Considerations for sound isolation, sound transmission, sound absorption and vibration control. Recommendations for industrial applications, critical listening spaces, mechanical system isolation, and ambient noise level control. Predictions and on-site measurements include Sound Transmission Loss (TL), Sound Transmission Class (STC), Noise Reduction Coefficient (NRC), and sound pressure levels.
